With the impending collapse of the Citadel, two members of the Resistance are tasked with evacuating any citizens remaining. Little do they know that their mission sees them gaining critical information that puts the early fate of White Forest in their hands.

Everything you see is in the image is straight out of the game. However in that specific scene the engine via shaders is handling Color Correction, Sharpening, Gaussian blurring passes over Bloom and slight amounts of edge AA to help clean things up.

We were going to wait till tomorrow to post this, but we have made a system to render expensive effects, but it's not run on your GPU. That's right. We've purchased expensive licenses from Adobe and can proudly present to you: a system for real-time photoshopping frames. The system is carefully designed so that the frames are fetched after being rendered by your GPU, then transmitted over your internet connection. Of course, this causes a slight lag, but that's why C17 requires at leasts a 20 mbit/s internet connection. Then when our central receive the data, our photoshoppers will process your game frames and apply the needed effects to the image, all this done in real-time. Then we will transmit back only the changes to your original image (delta-encoded), which then will be rendered by your monitor. We're quite excited about this technology, and we intend to post it on the Valve Developer Wiki as soon as we release C17.
